New low-profile magnet-activated rotary position sensor

Penny + Giles – a product brand of Curtiss-Wright Controls Industrial and leading designer and manufacturer of position sensors, solenoids and joysticks – has introduced two new in-cylinder linear transducers suitable for intelligent mobile hydraulics.

The ICT800 and ICT820 models combine the best features of the company's LVDT and potentiometer technologies into a single, rugged and reliable displacement transducer which, using contactless inductive coil technology, means both provide an almost limitless and maintenance-free working life with a class-leading body-to-stroke length ratio. Additionally, both the ICT800 and ICT820 models have signal conditioning integrated into the transducer's flange, which simplifies installation and eliminates interconnecting cables that can reduce the reliability of a control system. The ICT800 features 12bit resolution and operates from either an 8 to 30Vdc (unregulated) supply or a 5Vdc (regulated) supply and provides an absolute analogue output signal of either 0.5 to 4.5Vdc or 0.2 to 4.8Vdc over the selected measurement range. The transducer is factory configured for measurement range, output range and low-high output position; and uses an on-board microcontroller to linearise the transducer coil signal to less than ±0.1% non-linearity.
